Criminal Cases

Case Filing

Here we look at cases filed in Environmental Court by circuit and type of case. For cases involving more than one charge, the most severe charge was selected to define the case.

The following tables show cases filed in Environmental Court by Circuit and District Courts during the study period, categorized by type of charge. The charges have been grouped into \(12\) broader categories to provide a clearer and more concise representation. See the Appendix to review the mappings for how charges were grouped. As shown, the majority of cases were filed in District Courts.

Footnotes

  1. In previous reports, pre-2015 cases were lumped with 2015 data. In the current report, they are excluded, which is why there may be more of a gap between filings aross reports for 2015.↩︎

  2. Data is reported by fiscal year, covering a 12 month period running from July 1st of one year to June 30th of the following year, except for FY2025 data, which covers an 11 month period ending on May 31st. This report was published before the last month of data became available.↩︎
